Forgive me for suddenly posting, but as a Bronie, I feel the need to answer Saki's question. The sudden interest in My Little Pony is not actually an interest in My Little Pony persay, but in the recently released cartoon show My Little Pony: Friendship is Magic. The show is written primarily by Lauren Faust, who worked with famous animator Craig McCracken on both Powerpuff Girls and Foster's Home For Imaginary Friends, and was even the basis for the character of Frankie from FHFIF. In summary, she's amazing, which shows in MLP:FIM. The animation is incredibly well-done and the writing is really good. The show rather surprisingly is a cartoon embracing what many people enjoyed in old cartoons of the late 90's and early 00's. Not to mention Faust takes ideas for the show from both her Deviantart account and sometimes even 4Chan, which actually spawned a canon character by the name of Ditzy Doo. (Referred to as Derpy Hooves by fans on account of her misaligned eyes.) In short, it's the cartoon's fault.
Anyway, I won't be doing any Pony cosplaying being that I'm a guy and there are practically zero in the show aside from the dragon whom's name escapes me. However, if I see any of you, prepare to be photographed.
